I tested your code on Windows 11 via Parallels Desktop on macOS 15.7.7 and natively on macOS 15.7.7.
I hear

  • clipped sound on macOS
  • no clipped sound on Windows

On Ubuntu and Windows 11 (via Parallels Desktop on macOS 15.7.7) and on macOS 15.7.7, I tested the following code:

(
s.waitForBoot {
	SynthDef(\intentionalPeak, { |out = 0|
		var env = Env.sine.ar(Done.freeSelf) * 2 ! 2;
		var signal = SinOsc.ar * env;		
		Out.ar(out, signal);
	}).add;
	
	s.sync;
	
	s.record;
	
	s.sync;
	
	Synth(\intentionalPeak);
	
	2.wait;
	
	s.stopRecording;
}
)
  • On macOS, I hear clipped sound.
  • On Windows, I do not hear clipped sound.
  • On Ubuntu, I cannot judge exactly due to sound quality, but the sound seems to be clipped.

Windows seems to do extra processing against clipping…?
